Here’s what others say about our product.
This model/brand I feel like is a good starter for people wanted to get a ergonomic chair
but not wanting to invest a mortgage payment.
It comfortably seats two overweight poms
or one of my overweight behinds.
Overall I really like this chair
and would recommend
if you are looking for a more
affordable ergonomic chair.
The chair has a high mesh back, 3-way adjustable arms, an adjustable seat slide/slope & a 360 swivel gas lift. Not only can you do basic chair height adjustments but you can also adjust the seat to slide out or tilt for the perfect ergonomic fit. Its easily the most customizable chair I’ve ever used.
As a person who knows daily pain this chair is really nice at relieving it. It’s so easy to sit in this chair and be completely comfortable for hours. It’s lightweight and the mesh keeps you cool. I wasn’t sure what to expect but it’s a phenomenal chair.
When it comes to assembling furniture, I am not the best, but putting the chair together was very straightforward and it didn’t take no more than 20 minutes. This chair comes with an adjustable seat slide and slope, so you can customize it to how it fits you! It also comes with a height adjustable gas lift. The S-shape backrest prevents the body from back pain and creates a better posture for oneself. The high quality polyester stripe mesh provides a comfortable seating experience with good ventilation for a long-term use.
